My Kool-Aid experiments :)
See Craftster.org [ http://www.craftster.org/forum/index.php?topic=4268.0 ] for method help.
I used Jaegar Merino Aran [now discontinued] in cream - It came out fabulous I think. The fiery one is being used for a diagonal striped scarf [pics later].
I also tried 100% pure wool - colours came out matt and dull. Cream merino made them really vibrant and alive.
Going to stop now - Pop back later for more playing and fun in my shiny new blog of knitting joy!
